1) Rated average life is the length of operation (in hours) at which point an average of 50% of a large sample of lamps will still be operational and 50% will not.

2) Average life under specified test conditions with lamps turned off and restarted no more frequently than once every 3 operating hours. Lamp life is appreciably longer if lamps are started less frequently.
3) Average life under engineering data with lamps turned off and restarted once every 12 operating hours on a programmed start ballast. Lamp life is appreciably longer if lamps are started less frequently.
4) Approximate initial lumens.The lamp lumen output is based upon lamp performance after 100 hours of operating life, when the output is measured during operation on a high frequency reference ballast under

standard laboratory conditions. For expected lamp lumen output, commercial ballast manufacturers can advise the appropriate ballast factor for each of their ballasts when they are informed of the designated lamp.
The ballast factor is a multiplier applied to the designated lamp lumen output.

5) Design lumens are the approximate lamp lumen output at 40% of the lamp’s rated average life.This output is based upon measurements obtained during lamp operation on a reference ballast under

standard laboratory conditions.

This lamp is better for the environment because of its reduced mercury content. All Philips ALTO

®

lamps give you end-of-life options which can simplify and reduce your lamp disposal costs depending on your state and

local regulations.

Note:T5 VHO lamps have new miniature flat pin bases which require new GX5 sockets.

90% Lumen Maintenance

Philips T5 VHO Extreme Temperature Lamps

Footnotes from front page:
* 90% lumen maintenance at 17,500 hours for the T5 VHO lamp compared to 65% lumen maintenance at 8000 hours for the MH400/U lamp.

‡ 458 system watts (MH400/U) – 418 system watts (T5 VHO) = 40 system watts.
◊ 35,000 rated average life (T5 VHO at 12 hours per start) compared to 20,000 rated average life (MH400/U at 13 hours per start)
** For example, with 7200 initial lumens, you only need (4) 95W T5 VHO lamps instead of (6) T5 54W HO lamps when replacing a standard 400W HID System.

** For example, with 7500 initial lumens, you only need (4)

95W T5 VHO lamps instead of (6) T5 54W HO lamps when replacing a standard 400W HID System.
